YK series pressure switch (also known as pressure controller) is developed by using special materials, special craftsmanship and learning from the technical advantages of similar products at home and abroad. It is a relatively advanced micro switch in the world.This product has reliable performance and easy installation and use. It is used in heat pumps, oil pumps, air pumps, air-conditioning refrigeration units and other equipment that needs to adjust the pressure of the medium by itself to protect the pressure system.

When the pressure of the controlled medium in the system rises above the set value, the system pressure drives the mini-butterfly metal diaphragm to quickly produce instantaneous displacement, pushing the switch to turn off (or turn on), thereby providing over-high pressure protection.

When the pressure of the controlled medium is lower than the set value, the micro-diaphragm quickly jumps in the reverse direction and returns to the original state, and the switch is turned off (or turned on), thereby playing the role of over-low pressure protection.

Mainly used in air conditioning and refrigeration systems, vacuum pressure control systems, water pressure control systems, steam pressure control systems, oil and gas pressure control systems, etc.,prevent the pressure in the system from being too high or too low to ensure that the system is always within a safe working pressure range.

Supporting use in “YL equipment air compressor”, “air conditioning and refrigeration equipment”, “heat pump water heater equipment”, “vacuum pump vacuum tank equipment”, “industrial gas separation equipment”, “hydraulic-air pressure control equipment”, “steam pressure control” , “Welding Equipment”, “Water Pump Control”, “Spray Irrigation Automatic Control System”, “Air Compressor-Compressor”, “Automotive Control System”, “Coffee Maker-Wall Boiler”, “Special Mechanical Industrial Equipment” , “Ship-Aircraft-Train Pressure Control Equipment”, “Military Pressure Control Equipment-Fire Fighting Pressure Control Equipment”, “Pure Water Equipment-Wastewater Treatment”, “Aviation Special Pressure Control Equipment” and other equipment that need to monitor and measure the pressure in the control system.
